CVE-2026-81945 (GCVE-0-2026-81945)

Vulnerability from nvd – Published: 2026-09-18 15:19 – Updated: 2026-09-26 13:29

Title

PLANET IGS-5225-8P2T4S V1/V2 Admin Stack-Based Buffer Overflow via Web Server

Summary

PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 contain a stack-based buffer overflow in the web server. Insufficient bounds checking on data copied into a stack buffer allows a remote administrator to cause a denial of service or potentially execute arbitrary code on the underlying operating system.

CVE-2026-81944 (GCVE-0-2026-81944)

Vulnerability from nvd – Published: 2026-09-18 15:18 – Updated: 2026-09-18 17:53

Title

PLANET IGS-5225-8P2T4S V1/V2 Stack-Based Buffer Overflow via Web Server

Summary

PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 contain a stack-based buffer overflow in the web server. Insufficient bounds checking on data copied into a stack buffer allows a remote authenticated attacker to cause a denial of service or potentially execute arbitrary code on the underlying operating system.

CVE-2026-77218 (GCVE-0-2026-77218)

Vulnerability from nvd – Published: 2026-08-28 15:34 – Updated: 2026-09-01 20:28

Title

PLANET GS-4210-16P2S V3 Stack Buffer Overflow via dispatcher.cgi Credential Handlers

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains authenticated stack buffer overflow vulnerabilities in /cgi-bin/dispatcher.cgi. The web_login_first_post handler copies the usrPass POST parameter into a fixed-size stack buffer without length validation, the web_sys_enablePasswd_post handler copies the enbPass POST parameter into a fixed-size stack buffer without length validation, and the web_sys_localUser_post handler copies the usrName and usrPass POST parameters into fixed-size stack buffers without length validation. A remote authenticated attacker can send a crafted request to crash the CGI process or web management service, resulting in denial of service.

Title

PLANET GS-4210-16P2S V3 Stack Buffer Overflow and NULL Pointer Dereference via dispatcher.cgi RADIUS Handlers

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains authenticated stack buffer overflow and null pointer dereference vulnerabilities in /cgi-bin/dispatcher.cgi. The web_radiusSrv*_post family of handlers copies the radKey, radKey_0, radDftParamKey, radName, and radIp POST parameters into fixed-size stack buffers without length validation, and additionally dereferences radName and radIp without verifying their presence in the request. A remote authenticated attacker can send crafted requests to crash the CGI process or web management service, resulting in denial of service.

Title

PLANET GS-4210-16P2S V3 Stack Buffer Overflow via dispatcher.cgi Standard Handlers

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains multiple authenticated stack buffer overflow vulnerabilities in /cgi-bin/dispatcher.cgi. The following handlers copy attacker-controlled POST parameters into fixed-size stack buffers without length validation: web_vlan_membership_edit_dialog_post; web_dai_vlan_post; web_poe_alive_rmtip_post; web_sys_sntp_post; web_tool_upgradeManager_post; web_port_countersClr_post; web_rmon_statisticsClr_post; web_cablediag_copper_post; web_aaa_*Authlist* handlers; web_acl_mgmt_Rules_Apply_post; web_acl_mgmt_Rules_Edit_post; web_acl_*AceDel_post handlers; web_acl_*AceAdd/Edit_post handlers; web_acl_bindAdd_post; web_acl_bindEdit_post; web_snmp_v3view_add_post; web_snmp_v3group_add_post; web_snmp_v3community_add_post; web_snmp_v3host_add_post; web_snmp_notifyv3_add_post; web_snmp_v3user_add_post; web_snmpv3_remote_engineId_add_post; web_stp_globalSetting_post; web_isg_db_post; web_tacplus*_post handlers; web_dhcp_option82_post; and web_dhcp_port_option82_cid_post. A remote authenticated attacker can send crafted requests to crash the CGI process or web management service, resulting in denial of service.

CVE-2026-75125 (GCVE-0-2026-75125)

Vulnerability from nvd – Published: 2026-08-28 15:32 – Updated: 2026-09-01 20:28

Title

PLANET GS-4210-16P2S V3 Null Pointer Dereference DoS via dispatcher.cgi web_poe_alive_rmtip_post

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains an authenticated null pointer dereference vulnerability in /cgi-bin/dispatcher.cgi. The web_poe_alive_rmtip_post handler dereferences the rmtIP parameter without verifying its presence. A remote authenticated attacker can send a crafted request omitting the rmtIP parameter to cause the CGI process to dereference a null pointer and crash, resulting in denial of service of the web management interface.

CVE-2026-75124 (GCVE-0-2026-75124)

Vulnerability from nvd – Published: 2026-08-28 15:32 – Updated: 2026-09-01 20:27

Title

PLANET GS-4210-16P2S V3 Memory Corruption via dispatcher.cgi _readHttpParam

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains a pre-authentication memory corruption vulnerability in the web management interface where the _readHttpParam function copies an oversized HTTP query string without guaranteeing NUL termination, allowing parse_query_string to process attacker-controlled data into a fixed-size stack buffer. An unauthenticated remote attacker can send an oversized GET request to dispatcher.cgi to cause denial of service of the web management interface and potentially trigger memory corruption.

Severity

8.7 (High)

Title

PLANET GS-4210-16P2S V3 Command Injection via dispatcher.cgi web_smtp_test_post

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains an authenticated OS command injection vulnerability in /cgi-bin/dispatcher.cgi. The web_smtp_test_post handler incorporates a caller-supplied SMTP server value directly into a shell command without sanitization. A remote attacker with administrator web credentials can send a crafted SMTP server value to execute arbitrary operating-system commands on the device.

Vulnerability from cvelistv5 – Published: 2026-09-18 15:19 – Updated: 2026-09-26 13:29

Title

PLANET IGS-5225-8P2T4S V1/V2 Admin Stack-Based Buffer Overflow via Web Server

Summary

PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions before 1.2412b260707 and 2.2412b260519 contain a stack-based buffer overflow in the web server. Insufficient bounds checking on data copied into a stack buffer allows a remote administrator to cause a denial of service or potentially execute arbitrary code on the underlying operating system.

CVE-2026-77218 (GCVE-0-2026-77218)

Vulnerability from cvelistv5 – Published: 2026-08-28 15:34 – Updated: 2026-09-01 20:28

Title

PLANET GS-4210-16P2S V3 Stack Buffer Overflow via dispatcher.cgi Credential Handlers

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains authenticated stack buffer overflow vulnerabilities in /cgi-bin/dispatcher.cgi. The web_login_first_post handler copies the usrPass POST parameter into a fixed-size stack buffer without length validation, the web_sys_enablePasswd_post handler copies the enbPass POST parameter into a fixed-size stack buffer without length validation, and the web_sys_localUser_post handler copies the usrName and usrPass POST parameters into fixed-size stack buffers without length validation. A remote authenticated attacker can send a crafted request to crash the CGI process or web management service, resulting in denial of service.

CVE-2026-77217 (GCVE-0-2026-77217)

Vulnerability from cvelistv5 – Published: 2026-08-28 15:34 – Updated: 2026-09-01 20:28

Title

PLANET GS-4210-16P2S V3 Stack Buffer Overflow and NULL Pointer Dereference via dispatcher.cgi RADIUS Handlers

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains authenticated stack buffer overflow and null pointer dereference vulnerabilities in /cgi-bin/dispatcher.cgi. The web_radiusSrv*_post family of handlers copies the radKey, radKey_0, radDftParamKey, radName, and radIp POST parameters into fixed-size stack buffers without length validation, and additionally dereferences radName and radIp without verifying their presence in the request. A remote authenticated attacker can send crafted requests to crash the CGI process or web management service, resulting in denial of service.

Title

PLANET GS-4210-16P2S V3 Stack Buffer Overflow via dispatcher.cgi Standard Handlers

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains multiple authenticated stack buffer overflow vulnerabilities in /cgi-bin/dispatcher.cgi. The following handlers copy attacker-controlled POST parameters into fixed-size stack buffers without length validation: web_vlan_membership_edit_dialog_post; web_dai_vlan_post; web_poe_alive_rmtip_post; web_sys_sntp_post; web_tool_upgradeManager_post; web_port_countersClr_post; web_rmon_statisticsClr_post; web_cablediag_copper_post; web_aaa_*Authlist* handlers; web_acl_mgmt_Rules_Apply_post; web_acl_mgmt_Rules_Edit_post; web_acl_*AceDel_post handlers; web_acl_*AceAdd/Edit_post handlers; web_acl_bindAdd_post; web_acl_bindEdit_post; web_snmp_v3view_add_post; web_snmp_v3group_add_post; web_snmp_v3community_add_post; web_snmp_v3host_add_post; web_snmp_notifyv3_add_post; web_snmp_v3user_add_post; web_snmpv3_remote_engineId_add_post; web_stp_globalSetting_post; web_isg_db_post; web_tacplus*_post handlers; web_dhcp_option82_post; and web_dhcp_port_option82_cid_post. A remote authenticated attacker can send crafted requests to crash the CGI process or web management service, resulting in denial of service.

CVE-2026-75125 (GCVE-0-2026-75125)

Vulnerability from cvelistv5 – Published: 2026-08-28 15:32 – Updated: 2026-09-01 20:28

Title

PLANET GS-4210-16P2S V3 Null Pointer Dereference DoS via dispatcher.cgi web_poe_alive_rmtip_post

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains an authenticated null pointer dereference vulnerability in /cgi-bin/dispatcher.cgi. The web_poe_alive_rmtip_post handler dereferences the rmtIP parameter without verifying its presence. A remote authenticated attacker can send a crafted request omitting the rmtIP parameter to cause the CGI process to dereference a null pointer and crash, resulting in denial of service of the web management interface.

CVE-2026-75124 (GCVE-0-2026-75124)

Vulnerability from cvelistv5 – Published: 2026-08-28 15:32 – Updated: 2026-09-01 20:27

Title

PLANET GS-4210-16P2S V3 Memory Corruption via dispatcher.cgi _readHttpParam

Summary

PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains a pre-authentication memory corruption vulnerability in the web management interface where the _readHttpParam function copies an oversized HTTP query string without guaranteeing NUL termination, allowing parse_query_string to process attacker-controlled data into a fixed-size stack buffer. An unauthenticated remote attacker can send an oversized GET request to dispatcher.cgi to cause denial of service of the web management interface and potentially trigger memory corruption.
